Description

Technical Field

[0001] This utility model belongs to the field of tire technology and relates to a tire RFID electronic tag. Background Technology

[0002] RFID electronic tags are widely used in tire identification and recording. Tires with RFID electronic tags can be monitored in real time, enabling tire identification and anti-theft, recording of service life, usage and maintenance status, and so on.

[0003] Commonly used implantable RFID tags are implanted during the tire manufacturing process. Therefore, they are subjected to tire deformation and high temperature during tire use. Existing tags are mostly connected to the chip substrate and antenna. Due to the limitations of their own materials, their strength limit for deformation and high temperature resistance is low and difficult to exceed, resulting in unsatisfactory service life and reliability.

[0006] A tire RFID electronic tag includes a carrier plate, a chip, an antenna, and a sleeve. The chip is disposed on the carrier plate, the antenna is connected to the carrier plate and soldered to the pins of the chip, and the carrier plate is inserted into the sleeve.

[0007] Furthermore, it also includes an insulating sleeve disposed between the sleeve and the carrier plate.

[0008] Furthermore, the axial length of the sleeve is greater than the length of the carrier plate.

[0009] Furthermore, a bonding adhesive is disposed on the carrier board, and the bonding adhesive covers the chip.

[0010] Furthermore, the antenna has a spiral structure.

[0011] Furthermore, the carrier board has an end portion for insertion into the antenna along the axial direction of the antenna, and solder joints are provided on the carrier board to connect the pins of the chip and the periphery of the antenna.

[0012] Furthermore, the number of antennas is set to two, and they are symmetrically connected to both sides of the carrier plate.

[0013] In summary, the advantages of this utility model are as follows:

[0014] This invention employs a sleeve, which rigidly wraps around the carrier plate, allowing the sleeve to withstand the deformation and high temperature of the tire, thereby effectively protecting the carrier plate and greatly improving the service life of the electronic tag.

[0018] The following specific examples illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. This utility model can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this utility model. It should be noted that, unless otherwise specified, the following embodiments and features described therein can be combined with each other.

[0019] It should be noted that the illustrations provided in the following embodiments are only schematic representations of the basic concept of the present invention. Therefore, the drawings only show the components related to the present invention and are not drawn according to the number, shape and size of the components in actual implementation. In actual implementation, the form, quantity and proportion of each component can be arbitrarily changed, and the layout of the components may also be more complex.

[0020] In this embodiment of the invention, all directional indicators (such as up, down, left, right, front, back, horizontal, vertical, etc.) are only used to explain the relative positional relationship and movement of each component in a specific posture. If the specific posture changes, the directional indicator will also change accordingly.

[0021] Due to installation errors and other reasons, the parallel relationship referred to in the embodiments of this utility model may actually be an approximate parallel relationship, and the perpendicular relationship may actually be an approximate perpendicular relationship.

[0022] This utility model provides a tire RFID electronic tag, including a carrier plate 1 and an antenna 2 connected to each other, which is embedded inside the tire and serves as a unique identifier for each tire.

[0023] A chip 11 is disposed on the carrier board 1. One end of the antenna 2 is electrically connected to the pin of the chip 11 by soldering, and the solder joint 12 is located on the carrier board 1, so that the antenna 2 and the carrier board 1 are fixed.

[0024] In this embodiment, the number of antennas 2 is set to two, and they are respectively set at opposite ends of the carrier board 1, so that the antennas 2 extend in two opposite directions to improve the radio frequency transmission performance. The chip 11 is set in the middle of the carrier board 1, and the two ends of the chip 11 form solder joints 12 with the two antennas 2 respectively.

[0025] Preferably, the carrier plate 1 has a strip structure with a set thickness and a set length. The two ends of the carrier plate 1 in the length direction are connected to two antennas 2. The antennas 2 have a spiral structure with an inner diameter greater than the thickness or width of the ends of the carrier plate 1, so that the ends of the carrier plate 1 can be inserted into the antennas 2 along the axial direction of the antennas 2, and the periphery of the antennas 2 is located on the outer periphery of the ends of the carrier plate 1. The solder joint 12 forms a wrapping connection between the periphery of the antennas 2 and the carrier plate 1.

[0026] The above-mentioned connection method makes the antenna 2 and the carrier plate 1 more integrated. Under the deformation of the tire during use, the stress on the antenna 2 and the carrier plate 1 is more uniform. In particular, when the antenna 2 deforms, most of the force is applied to the carrier plate 1 instead of the solder joint 12, thereby effectively preventing the solder joint 12 from breaking and falling off, and effectively enhancing the connection strength between the antenna 2 and the carrier plate 1.

[0027] The surface of the chip 11 is covered with bonding adhesive 13, which is cured and attached to the carrier board 1 to form encapsulation and protection for the chip 11.

[0028] Furthermore, a hollow cylindrical sleeve 3 is fitted around the outer periphery of the carrier plate 1, so that the length of the carrier plate 1 is inserted into the sleeve 3 along the axial direction. The axial length of the sleeve 3 is greater than the length of the carrier plate 1, thus forming external protection for the carrier plate 1, the antenna 2, and the solder joint 12.

[0029] The sleeve 3 is made of rigid material, preferably metal, which can effectively withstand the deformation and high temperature during tire use, maintain the stable structure of the sleeve 3, and ensure that the internal carrier plate 1 does not need to contact the tire material or withstand the deformation of the tire, thus greatly increasing its service life.

[0030] When the sleeve 3 is made of metal, two insulating sleeves 31 are respectively provided on the inner circumference of both ends of the sleeve 3. The insulating sleeves 31 are located between the inner circumference of the sleeve 3 and the outer circumference of the carrier plate 1, so as to prevent the solder joint 12 and the antenna 2 on the carrier plate 1 from directly contacting the sleeve 3 and to prevent the two antennas 2 from being conducted by the sleeve 3.

[0031] Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort should fall within the protection scope of this utility model.
